PNEUBATIC W'HTIEL AND HUB.

Specification of Letters Patent.

Application filed llovember 1, 1906 Serial No. 342,150.

I is a specification.

object is to provide a simple, strong v 1 A and durable Sll'lfiBl specially adapted for automobiles, and other vehicles, to prevent the jarring and. concussion incident to the use of carnages on rough roads.

My invention consists in the construction,

arrangement and combination of elements and sub-combinations hereinafter set forth, pointed out in my claims and 1llus trated in the accompanying drawings, in

Figure 1 is side view of the wheel from which part of an outer plate broken away to disclose two distinct and concentric parts of a hub and a pneumatic circular tube between them. Dotted lines indicate the motion of the inner and smaller part of the hub and the circumference of the wheel when the wheel is subjected to pressure and rotated on the axle. Fig. 2 is a vertical central sectional view that shows the positions of all the parts relative to each other and the upon which the wheel is mounted. Fig. 3 is a de tail view that shows an elastic metal rim on the ends of the spokes in place of a pneumatic tube shown in Fig. 2.

The numeral 16 designates an axle and 12 the inner part of e hub on the axle. It has a concave groove 111 its periphery and antifriction rollers 3 on bearers 14; fixedin its sides near its circumference and a pneumatic tube 15 in cave groove in the exterior of the inner part 12. A 1% is fitted onftle tube 15. Spokes .17 are fined on '1 an e 16 and a r1 i 18 onthe ends of the spokes for tube 19 as slmwu in. Fig.

To the outs le faces are fixed on olate 21, and the ill, by means oi bolts two plates coinciding circular openings nd screw threadediianges 22 hub portion, 16,

extending ou ards and adapted to receive .screw-threadcd caps 23 tor closing the open ings"; The caps have projections 24% tor applying a ion thereto as required for placing them o and taking them and.

means or be solid 12 on the axle,

a rollers 13 t en side and l rigid circular frame in any suitable the circular solid frame 16, the plates 20, having circular openings and flanges 22, are

fixed together and the caps 23 are detacl1-' ably placed on the flan es to reinforce the plates and to allow acce s to the rollers as required to facilitate repairing or replacing the rollers.

Patented 3am. 28, 1.908.

A tube 25 is connected with the outer hub hub 12 and 19 as required to relieve and pro tect to a great extent the outer tube 19 and to prevent jarring and concussion.

Having thus set forth the purposes of my invention and the construction, arrangement and combination of all the parts the practical operation and utility thereof will be obvious.

What I claim as new and desire to secure by Lettersatent, is v 1. In an elastic wheel, a solid hub having a continuous concave groovein its periphery and anti-friction rollers on its side faces, a solid circular frame having a continuous concave groove in its inner face, a pneumatic tube between. the hub and the circular frame and. the hub and the frame connected by circular plates fixed to theside faces of the circular frame and provided with openings for the purpose stated.

2. In an elastic wheel, a solid hub having outer part ofa hub having a continuous concentric groove in its inner circumference, a neuinatic tube between the parts of the ub, circular plates fixed to the side faces of the outer art of the hub, circular openings in said p ates, flanges projecting outwardem said openings and caps fitted to the flanges as set forth.

r. Agoneumatic wheel comprising an inner- Q ee'igeee part of a hub and an outer part of a hub, a and anti-friction rollers on the side faces of pneumatic tube between the two parts, the inner part of the hub to engage"said 10 plates fixed to the sides of the outer part of flanges, arranged and combined to operate the hub to extend over the sides of the inner as set forth.

5 part of the hub, s okes extending from the HAMILTON A. BRGWNL outer part of the ub, a rim on the ends of Witnesses: the spokes,. circular openings in the letes B. O. DU 1301s,

provided with flanges, caps on the anges HAL C. FULLER.
